I think that the weak link here is the GNSS assistance mechanism used in ubuntu.
Having a good assistance method the time to first fix should be within seconds or worst case a couple of minutes. Am I right? If the system is able to achieve <1min time to first fix, then you don't need to give the last known position to the client apps anymore. Now, let's say you are inside a building, then you need an alternative method to determine your location, like using visible cell towers or hotspots. Best Regards, Felipe.
